Should I Be Concerned?

My CZ-83 is a great shooting pistol but the mags...
When full or close to it the mags rattle. Not sure what causes it and can’t see any visible movement but something shakes inside them.

Every mag that is a double stack and for a pistol I have does the same thing. I don't think you need be concerned. ;)

I have two freinds that have that pistol and they both had the magazine rattle, but they have put a pile of ammo threw each one and never had a problem. I think you will be fine, BTW I shot one of them, and they are impresive, I am thinking of getting a CZ for my wife to carry.
